    (54) End fire aerial


    (57) An end-fire aerial (6) includes a broadside aerial array (7), for example a horn antenna. A block (9) of dielectric foam material extends outwards from the array (7), in a direction perpendicular to the array. The block (9) is designed to be of such dimensions, and of a suitably low dielectric constant such that it produces an end-fire gain.
